NVIDIA InfiniBand NDR200 OSFP to 4xOSFP Splitter Direct Attach Copper Cable

Overview

The NVIDIA MCP7Y50-N003 is a direct attach copper splitter cable designed to convert a single 800 Gb/s OSFP port into four separate 200 Gb/s OSFP links. It serves high-speed InfiniBand NDR and 400 GbE Ethernet networks by enabling multiple connections from one switch port to several servers or adapters. With a length of three meters and passive copper conductors, it provides a low-latency, power-free solution for short-range data center interconnects.

Key features

• Splits one 800 Gb/s twin port OSFP into four independent 200 Gb/s OSFP links, maximizing port utilization.
• Passive copper design eliminates power consumption and adds virtually no latency to the signal path.
• Supports two-channel 100G PAM4 signaling on each link to maintain signal integrity and bandwidth.
• EEPROM in every connector enables automatic detection and configuration of InfiniBand or Ethernet protocols by the switch.
• 26 AWG wiring enclosed in a low-smoke, zero-halogen (LSZH) jacket ensures safer cabling within racks and compliance with safety standards.
• Optimized for use with NVIDIA Quantum-2 or Spectrum-4 switches and ConnectX-7 adapters, ideal for GPU clusters, HPC nodes, and machine learning servers.

Key specs

• Port type: OSFP twin port to 4x OSFP breakout
• Cable length: 3 meters
• Conductor type: Passive copper, 26 AWG
• Signaling: Two-channel 100G PAM4 per link
• Jacket material: LSZH, halogen-free
• Compatibility: InfiniBand NDR and 400 GbE Ethernet networks

Connectivity and compatibility

This splitter cable connects directly to NVIDIA Quantum-2 or Spectrum-4 switches via the twin port OSFP plug. The four breakout OSFP connectors attach to servers or adapters equipped with ConnectX-7 cards, enabling multiple high-speed links without the need for transceivers or optical modules. The built-in EEPROM ensures seamless protocol recognition and configuration, simplifying network setup and management.

Installation and setup

Installation is straightforward and requires no additional components. Simply plug the twin port OSFP end into the switch and connect the four breakout OSFP ends to the target adapters. The passive copper design means no external power or cooling is needed, and the cable’s flexible LSZH jacket allows easy routing within racks or between adjacent racks. This makes it a practical choice for dense data center environments where space and efficiency are critical.

Ideal uses and environments

This cable is well suited to data centers running high-performance computing workloads, GPU clusters, and machine learning servers that demand high bandwidth and low latency. It fits well in short-range deployments where multiple 200 Gb/s links are needed from a single 800 Gb/s switch port. Network administrators looking to optimize port density and reduce complexity will find this splitter cable a reliable and efficient solution.
